pci_sriov_get_totalvfs() reports a VF count, not an errno-style status. It returns 0 when SR-IOV is unavailable or the device is not a PF, and otherwise returns the PF's driver_max_VFs value. driver_max_VFs is stored as a u16 in struct pci_sriov. It is derived from the SR-IOV TotalVFs field or from a driver-provided limit, so the implementation cannot return a negative value. Change the declaration, CONFIG_PCI_IOV stub, and implementation to return unsigned int.
